STATUS MENU
Data connection
Indicates whether the device has a mobile data connection or not
state
Connection type
Mobile connection type. Possible values are:
• 4G: 4G (LTE)
• 3G: 3G (WCDMA), 3G (HSDPA), 3G (HSUPA), 3G (HSPA), 3G (HSPA+), 3G (DC-HSPA+),
• N/A - not possible to determine at the moment
Signal strength
Received signal strength indicator (RSSI) measured in dBm. Values closer to 0 indicate a
better signal strength
Carrier Aggregation
LTE Advanced Carrier Aggregation, CA, is one of the key techniques used to enable the
very high data rates of 4G to be achieved.
By combining more than one carrier together, either in the same or different bands it is
possible to increase the bandwidth available and in this way increase the capacity of the
link.
Connected band
Currently used mobile frequency band.
Other signal level
Overall signal quality for different connection types is defined by different measurements.

3G (HSDPA+HSUPA), UMTS
- RSRP - reference signal received power, measured in dBm. Values closer to 0 indicate
better signal strength
- RSRQ - reference signal received quality, measured in dB. Values closer to 0 indicate
a better rate of information transfer
- SINR - signal-to-interference-plus-noise ratio, measured in dB. Higher values
indicate a better rate of information transfer
- EC/IO - downlink carrier-to-interference ratio. Values range from -20 to 0 (closer to
0 indicates better signal quality/cleanliness)
- RSCP - received signal code power. Values range from -124 to 0 (closer to 0
indicates better signal stength)
